.JFECIFICATION forming part of Letters Patent No. 303,182, dated August 5, 1884.

' Application filed December It, 1882. (No mod cl.)

To all whom it may concern.-

Be it known that I, GUSTAVUS A. PADDOOK, of Beaver Dam, in the county of Dodge and State of Wisconsin, have invented certain new and useful Improvements in Reels for Harvesting-lllachines; and I do hereby dc exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to reels for harvesting-machines, and more particularly to devices for giving avariable motion to thearms or heaters of such reels, whereby such beaters receive an accelerated motion at the time they are passing through the grain and a re tarded motion at or about the time of leaving it, the object of such variable motion being to cause the heaters to throw the grain quickly back over the cutters and to leave the grain slowly, so that it shall not be thrown by such heaters behind the machine or upon the back edge of the apron in self-binding harvesters.

The object of the invention is to provide an improved construction in the-devices above referred to; and it consists inthe matter hereinafter described, and pointed out in the.

two pieces or slats, E and E, which are arclainis.

In the drawings, Figure l is a side view of a reel constructed as proposed by my invention. Fig. 2 is a rear elevation of a portion of the same, showing two of the heaters and a portion of the cam-plate broken away. Fig. 3 is a plan view'of the reel-hub and shaftbearing, showing the bearing of thesame and the cam-plate in section. Fig. 4 is a detail side elevation showing the lever for adjusting the cam-plate and means for raising and low ering the reel. din

A is a standard for supporting the reel and its connecting parts, which is attached in a suitable position upon the frame of a reaper or harvester. I

In the drawings, Fig. 1, the reel and its tion with the cutter-bar A and apron of a self-binding harvester.

,To the top of the standard A is pivoted by means of a bolt, a, a forked lever, A", upon .ing 0, which may be actuated bya chain belt which the reelshaft B is mounted by means of boxes 0 G, bolted to the forked ends a a of the said lever.

Upon the standard A is placed a notched, segment, A, which extends upwardly at the side of the rearwardly-extending arm of the lever A". A spring catch or detent, (6, upon said lever is adapted to engage the notches upon the segment A, so that the lever A may be swung upon its pivot cand held in any de sired position, by which means the reel-shaft 13 upon the forked ends a a of said lever may be adjusted vertically and in reference to the cutter-bar of the machine. The detcnt a is operated by a rod connected to a bent lever, (6, arranged at the handle of the lover A in a well-known manner.

The recl-shaft Bis extended outside of its bearing 0, and has upon the extremity of its projecting portion ahead, D, having cast upon it four radial arms, D, to which the beater arms E of the reel are pivoted. A sprocketwheel, B, is shown upon the end of such shaft opposite to the reel and outside of the bearoperated from the operative parts of the machine; but thesaid reel-shaft may be operated in any desired manner.

The beaterarms E are each composed of ranged obliquely to the reel-shaft and crossed near their inner ends, and are pivoted to the arms D by means of pivot-pins c, which pass through apertures d in the ends of the arms D, and through lugs c and c" on the slats E and E The slats E are extended beyond their pivotal points 0, so as to form short arms E upon the ends of which are placed pins or friction-rollers 6 The said frictionrollers e are placed upon bearing-pins attached to plates 6', bolted to the ends of the said slats, the axes of said pins being parallel to the reelshaft B, and are adapted to move in a cam-groove, F, in a canrplate, F, attached to the bearing-box C upon the arm A. As shown in the drawings, the cam-groove F is made substantially concentric with the shaft of the reel for about one-half its circumference 1 and is curved between the points f and f toward the center of the cam-plate. hen, during the rotation of the reel-shaft, the rollers-c upon the beater-arms are traversing the concentric portion of the cam-groove, the beaterarms remainunchanged in position with reference to the reel-shaft, but upon reaching the irregularly-curved portion at f the inner ends of the beater-arms are carried inwardly toward the axis of the shaft, and their outer ends are swung rapidly toward the rear,"thus giving an accelerated motion to the ends of the said beaterarms. The continued revolution of the reelshaft then carries the roller (2 away from the axis of the shaft until the concentric portion of the cam-groove is again reached at f. During this latter movement the motion of the outer end of the beater-arm is retarded with reference to the general motion of the reel shaft. The accelerated and retarded movement described is preferably arranged to take place at the time the beater'is passing over the cutter-bar of the harvester, so that the grain will be thrown back quickly over the cutters and the heaters will leave it with a slow motion.

In order to provide means for changing the position in which the variable motion of the heaters takes place with reference to the cutter-bar, the cam-plate F,which gives the variable motion to the beater-arms, is made adjust able upon its bearings on the standard A. For this purpose the said cam-plate is attached to the bearing-box C, so that it may be partially rotated thereon by means of a grooved collar, f, which is bolted to the outer side of the plate F, and which fits over a flange, c,

upon the stationary bearing 0. The caniplate F is held in position and is adapted to, be moved by means of a lever, G, which isbolted to the upper portion of the side of such accelerated movement of the heaters occurs may be varied, as desired, according to the conditions of the grain or other circumstances. Upon the standard A is bolted a spring, I, the free end of which rests against the under side of theend of the short arm a of the lever A and under the reel-shaft bearing. The effect of this spring is to tend to force the end of the lever upward; and its object is to assist the operator in raising the reel, and also to support the end of the lever A when the detent a? is released from the notched segment A in the operation of adjusting the reel in reference to the cutter-bar. I

I am aware that devices have been hereto.- fore used for varying the speed of the beaterarms in harvester-reels, in. which said arms are pivoted loosely to radial arms upon a reelshaft, and hang vertically, so as to revolve upon their pivots during the rotation of the reel, the outer ends of said arms beingthrbwn plate F upon its axis the place at which the bar, by the action of short stationary cam-surfaces, constructed to engage projections upon said arms above their pivoted points. My invention does not, therefore, embracea construction similar to that above described, but is restricted to a device in which the beaterarms are held positively in position during the entire rotation of the reel, and oscillated upon their pivotal points through ashort are only.

A reel having its arms and beater-blades rigidly secured to the reel-shaft may obviously be combined with mechanism by which the speed of the blades may be intermittingly accelerated and retarded; but, for the double purpose of producing such variation and for changing the points of variation, I prefer to make the blades independently variable in their movement, as herein shown, for the rea son, among many, that-the variation of the motion of a single blade may be effected by a less expenditure of power than would be required to effect the same change in the motion of the entire reel structure.

I claim as my invention 1. In a harvester-reel, the combination of the reel-shafthaving radial arms D, beaterarms E, pivoted to said arms, and provided with roller-pins e, and a grooved cam-plate, 'F, engaging said roller-pins, and adapted to give an oscillatory motion to said arms, substantially as described.

2. The combination of the reel-shaft having radial arms D, beaterarms E, pivoted to said arms, and consisting of crossed strips E E, the strips E extending inwardly from the pivotal points of the beater-arms, to form arms E and roller- )ins 6 carried b said arms substantially as described.

3. The combination of the bearing-box O for the reel-shaft, having an annular. flange, c, the cam-plate F, provided with a collar, f, adapted to embrace the flange, and an adjusting-lever, G, substantially as described.

4. In aharvester, the combination of a reel standard, a vertically-movable support carried by said standard, and provided with bearings for the reel-shaft, means for adjust ing said support vertically and holding it in its adjusted-position, and a spring attached to. the standard and acting against said reelthe weight of the reel, substantially as described. 1

In. testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
